block: keep a list of block jobs
The current way to obtain the list of existing block jobs is to
iterate over all root nodes and check which ones own a job.
Since we want to be able to support block jobs in other nodes as well,
this patch keeps a list of jobs that is updated every time one is
created or destroyed.
